I have a 2007 Azera that I just replaced the battery and starter in,all the lights work, clock still works, and the remote opens the door. But, the car wont start. Help please!

 

Does the engine crank? And not start?
Or, does the engine crank and not start?

If it does not crank then check the battery and terminals for corrosion.
See if there is a bad ground. Test light on negative terminal and the light touching the engine block, then crank. If Test light bulb lights up then bad ground.
If not then check the starter relay. See youtube videos on how to test a (starter) relay

If engine cranks but does fire up then check for the basics
Fuel, spark, compression, timing, exhaust (blockages)

 

Does the engine crank?

 

Yeah, would have help others if the person would have came back for an update or fix
